[BBv2] [msvc] architecture settings

From: Reece Dunn (msclrhd_at_[hidden])
Date: 2005-10-17 03:28:51

The IDE for msvc sets the /machine linker flag to the target machine 
(X86, SH3, etc.) and also adds a define for the architecture being 
compiled such as _AMD64_. This patch adds that support for BBv2.
